MACHINE FOR SAWING STICKS-FOR BROOM-I-IAND'LES.

Specification of Letters Patent No. 10,023, dated September 20, 1853.

To @Z w/zom t may concern Be it known that I, THOMAS J. ALEXAN- DER, ofWesterville, in the county of Franklin and State of Ohio, have inventeda new and Improved Machine for Sawing Sticks for Broom-Handles,Chair-Bounds, &c.; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, in which Figure l, is aside elevation of the machine.Fig. 2, is a plan or top view of the same. F ig. 3, is a transversevertical sec tion of the same, taken at the line, X X, in Figs. l, and2.

Similar letters of reference indicate corresponding parts, in each ofthe several figures.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A, represents a rectangular frame, constructed in any suitable manner;and B, is a. horizontal saw, placed on a vertical shaft, C; the saw, B,extending a short distance above the bedpiece, D, on the upper part ofthe frame, A.

E, E, are two vertical saws, hung on one and the same shaft, F,which isplaced transversely in the frame, A, the bearings being in the siderails of the frame. The vertical saws are under the horizontal saw, B,and are so placed that their tops nearly touch the horizontal saw; theedge of the saw, B, extending over both saws, E, E; this is clearly seenin Fig. 3. The three saws may be driven in any proper manner.

G, represents a frame, which is placed on ways (c) (a) on the upper partof the frame, A. This frame, Gr, has a reciprocat ing motioncommunicated to it, in any proper manner. The top crosspiece, H, of theframe, swings or turns on the upright, (b), (b). Through the crosspiece,H, two screw-rods, I, I, pass, having circular nuts, (c), (c), uponthem, above the crosspiece. Between the screw-rods, and at their lowerends, is secured the lo-g, J, which is to be sawed into sticks. The log,J, may be secured between the lower ends of the screw rods, in anyproper manner. The lower ends of the screw-rods may be provided withspurs, which may be driven into the ends of the log,

K, (see Fig. 1,) is a vertical shaft, attached to the frame, G. Thisshaft, K, has a crank, L, at its lower end, and a pulley, (CZ), o-n itsupper end, above the cross-piece, H. A rope or cord, (e) passes aroundthe pulley, (Z,) and also around the circular nuts, (c), (c), and apulley, Now, it will be seen that, by turning the crank, L, the pulleys,(di), and (f), and also the circular nuts will be turned; and the screwrods, I, I, and the log, J, will consequently be elevated or depressedaccording to the direction in which the crank is turned.

The operation of the machine will be readily understood. The log, J,being secured between the lower' ends of the screwrods, the frame, Gr,is moved toward the saws; the log J, having been previously adjusted theproper height by operating the crank, L. When the log, J, comes incontact with the saws, a square stick is sawed from it, as will readilybe seen by referring to the position of the saws, as seen in Fig. 3.lNhen the frame, Gr, is moved back, the log is moved or swung toward thesaw; it being recollected that the crosspiece, H, turns on the upperparts of the uprights, (b), (b) the frame, Gr, is then again movedforward, and a second stick is sawed from the log; and so on. When onetier or course is sawed from the log, the log is depressed by operatingthe crank, L, and a second tier or course is sawed from the log. A gage,M, is attached to the bedpiece, D, against which the log rests, in orderto regulate the size of the sticks and allow the log to be properlyplaced as regards its position with the saws.

By 'the specified combination and arrangement of the elevated swingingframe with the clamping screws forming long radius rods and coupled andoperating as described, great facility is afforded for lifting andsetting the log to its work, as, by bearing laterally on the handle (L)while turning it to run down the screws, the latter are swung outwardand lowered simultaneously so that they'may be hitched expeditiously tothe log whatever its lateral position on the table of the machine and,by turning the handle (L) so as to elevate the screws, the log made toswing itself to its required position against the gage and the log fromtime to time adjusted laterally and vertically to give it its properposition in relation to the saws for the performance of the several cutsby bearing laterally on the handle simultaneously with the turning ofit, whereby the time and labor usually consumed in lifting or slidingthe heavy log laterally on the bed and adjusting it to its several sets,byvertical and lateral movements separately performed, are obviated.This easy and eX- peditious handling of the log is of much practicalimportance in the operation of these machines.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- The method herein described of handlingand adjusting the log to its place and to its various positions for theseveral cuts, by. means of the radius rods or clamping screws coupledand operated as specified and suspended by a swinging frame from abovearranged and operating together as herein set forth, so that, by bearinglaterally on the screw lever or handle while turning it, the clampingscrews are swung laterally and raised' or lowered, simultaneously, toapproach the log on the table and convey it with facility to the gage,and t0 adjust the log expeditiously, when under operation, to itsVarious sets, laterally and vertically, as shown and described. y
